Description of Related Art

Exposing a cell phone to an outside heat source is the most common cause of overheating. Leaving a phone sitting directly in the sun, inside a hot car or under a lamp that produces heat can cause the phone to feel hot to the touch. Particularly harmful is to expose the battery to heat when it is fully charged, as the battery will be periodically checked and charged back up to 100 percent, applying stress. Depth of discharge also affects battery life, meaning it is best not to let the charge run down to zero percent. Anything over about 30 degrees centigrade will start negatively impacting a lithium-ion battery, and this is a temperature phones typically climb above every time charging occurs.

With temperatures consistently reaching the high nineties or more, leaving a phone in a vehicle can quickly lead to overheating. If a phone needs to be left in a vehicle, it should be tucked away in a shady spot. This protective action may not completely stop the phone from reaching high temperatures, but it will be much safer than leaving it in direct sunlight.

It is known that smart phones are sensitive to environmental conditions. By way of example, temperatures in excess of 95° Fahrenheit, as well as temperatures less than 32° Fahrenheit, can negatively affect the performance of a cell phone. Some smartphones list the optimum range of temperatures in their technical specification. For example, when the phone is turned off, an iPhone can withstand temperatures between −4° and 113° Fahrenheit. When the phone is turned on, the range is much narrower. Apple suggests 32° Fahrenheit as the lowest operating ambient temperature. Other phones are rated for much lower temperatures, and some can go as low as −4° Fahrenheit while in operation.

When lithium-ion batteries are exposed to cold temperatures, their performance suffers. When cold, a phone battery can drain faster than normal or it might indicate it has ample power remaining and then suddenly go dead. The problems are only temporary and the battery should behave normally when the device is brought back up to warmer temperatures. Heat affects mobile phones, mobile laptops and mobile tablets that are exposed to the sun or heat when, for example, they are exposed to direct sun when located on a boat or left in a car during the summertime. Cold affects mobile phones, mobile laptops and mobile tablets that are exposed to cold ambient temperatures when, for example, being utilized on a ski slope.

Dropping a cell phone can cause damage to multiple portions of a cell phone. Cracked glass is one of the most common forms of damage to broken cell phones. The glass can crack when a phone is dropped or accidentally stepped on, or crushed while leaning against an object. Manufacturers are trying to make cell phones sturdier as the devices become more advanced, but smartphone screens are still made of breakable glass.

Dropping of a cell phone can affect the cell phone buttons. Buttons that do not work or stick are functionally problematic. Nonfunctioning buttons affect the ability to text, search the Internet, and dial the phone. Buttons may stop working because of a cell phone's circuits being exposed to moisture or heat, or become broken as a result of a drop.

Cell phone speakers can stop working due to loose or corroded internal parts, or damaged hardware from dropping the phone. There is a need for an environmentally protective sleeve for a cell phone, smart phone, laptop, or tablet that protects these mobile electronic devices from overheating, extreme cold, damage from being dropped, and damage from water.

Thermal signatures (such as an IR signature) are known, as are ways to mask the thermal signature with a reflective material like that of metalized Mylar. Such masking has been utilized for security, military and law enforcement. However, while masking the thermal signature of the individual or a piece of equipment such as a military tank, the reflective material draws attention to an adverse distant observer by way of its reflection of light. There is a need for a material that will mask a thermal signature while minimizing reflective light. Such material, as taught herein, may also be used to protect an electronic device from damage.

SUMMARY OF THE INVENTION

According to embodiments, the present invention provides a protective sleeve for an electronic device. The protective sleeve may have multiple layers, including a reflective layer, one or more insulating or durability layers, which may include a buoyant layer, and a protective layer. In embodiments, the layers may also be referred to as surfaces. In embodiments, the reflective layer is the outermost layer. The reflective layer can be made of metalized Mylar® or a material with similar reflectivity and can have an emissivity within a range of about 0.05 to 0.40. In embodiments, the protective sleeve includes a buoyant layer disposed between the outermost layer and an innermost layer, which can be made of foam or other buoyant material with a thickness in the range of about 0.12 inches to 1 inch. In embodiments, the protective layer is the innermost layer (i.e. closest to the electronic device) and is made of fleece, microfleece, or similar material. In embodiments, the innermost layer containing fleece or microfleece can serve as an insulating layer or as both an insulating layer and a protective layer. In embodiments, the protective sleeve can include only 2 layers of those described above, or can include 3 or even 4 or more layers. According to embodiments, the electronic device that is housed by the thermal protective sleeve is a smart phone, cell phone, laptop, or tablet.

According to other embodiments, the present invention provides a protective sleeve for an electronic device where the outer layer comprises a printed layer and/or colored layer. A reflective layer can be located beneath the printed outer layer. The outer layer may be composed of nylon or similar material. In embodiments, the layers of the protective sleeve are arranged from the outermost to innermost layers according to a first layer which is a colored material; a second layer which is a reflective material; a third layer which is nylon ripstop or similar material; a fourth layer which is foam; and a fifth layer which is microfleece. In other embodiments, the colored material can be printed. In other embodiments, the layers of the protective sleeve are arranged from the outermost to innermost according to a first layer which is a colored material; a second layer which is a reflective material; a third layer which is foam; and a fourth layer which is microfleece. In other embodiments, the protective sleeve can have an arrangement of layers from the outermost to innermost layers as follows; a first layer which is a reflective material; a second layer which is nylon ripstop or similar material; a third layer which is foam; and a fourth layer which is microfleece. Any combination of these types of layers is feasible depending on the application and additional or fewer layers can be included.

According to embodiments, the emissivity of the protective sleeve may be in the range of 0.05 to 0.6, including 0.4 to 0.6, 0.2 to 0.4, 0.3 to 0.5, 0.05 to 0.2, and so on. Further, the thermal protective sleeve as disclosed herein is capable of protecting an electronic device within a range of negative 32° Fahrenheit to 300° Fahrenheit.

According to various embodiments, the reflective layer may be a laminate which includes two materials: a highly reflective continuous metalized Mylar® polyester film (such as aluminized polyester film) laminated to Rip Stop Nylon or similar material.

Various features and advantages of the invention, only some of which are discussed herein, are described as follows according to embodiments. In embodiments, the protective sleeve is capable of providing thermal protection which protects the mobile electronic devices from overheating in direct and indirect sunlight and high ambient temperatures. Further, in embodiments, the protective sleeve is capable of floating in water, with or without a mobile electronic device inside. Additionally, in embodiments, the protective sleeve is capable of reflecting infrared (IR) and ultraviolet (UV) heat from sunlight. Further, in embodiments, the protective sleeve is capable of providing access to charging ports on the electronic device, allowing a user to stream Bluetooth® data, and/or allowing a user to send and receive phone calls and other data during use. Still further, in embodiments the protective sleeve is capable of providing drop/shock protection during use.

Further, according to embodiments, the protective sleeve is capable of being used with or without a protective case housing the device. Additionally, according to embodiments, the protective sleeve is capable of providing insulation from extreme cold such that it is capable of preventing the device from freezing when temperatures are below 32° F. Additional embodiments include a feature such as a user ID tag for the owner to place initials or other identifying information on the tag.

Additional embodiments include a thermal masking material which includes a colored or printed outer layer and a continuous metalized reflective layer such as a metalized reflective polyethylene terephthalate (PET) film (e.g. Mylar®) disposed beneath the colored or printed outer layer as an inner liner. In embodiments, the continuous metalized reflective material is laminated to a Rip Stop Nylon material or similar material. In embodiments, the reflective layer is disposed between an inner liner and an outer surface layer as a middle layer. The thermal masking material can have a variety of uses such as a sniper blind, camouflage clothing, or camouflage covering.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS OF THE INVENTION

Reference will now be made in detail to various exemplary embodiments of the invention. It is to be understood that the following discussion of exemplary embodiments is not intended as a limitation on the invention. Rather, the following discussion is provided to give the reader a more detailed understanding of certain aspects and features of the invention.

As used herein, the term “about” is understood as within a range of normal tolerance in the art, for example within 2 standard deviations of the mean. The term “about” can be understood as within 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, 0.1%, 0.05%, or 0.01% of the stated value. Unless otherwise clear from the context, all numerical values provided herein are modified by the term “about.”

As used herein, the term “metallized” (as in “metallized” Mylar®) refers to a material such as a polymer film which has been coated with a thin layer of metal, such as aluminum, chromium, or nickel, typically through a physical vapor deposition (PVD) process. The thin layer of metal can be coated on one surface of the material or both surfaces.

As used herein, the term “laminated” (or variations including “laminate”, “lamination”, and the like) refers to the process or result of creating a composite material by joining two layers together, typically under heat and pressure and through use of an adhesive.

As used herein, “Mylar®” may be used interchangeably with “biaxially-oriented polyethylene terephthalate (PET) film”, “polyethylene terephthalate (PET) film”, “polyester film”, and similar terminology.

According to embodiments, the protective sleeve may include two layers (outer, inner), three layers (outer, middle and inner), or four layers (outer, first middle layer, second middle layer, inner layer). In embodiments, the protective sleeve may include one or more layer of material in any number of layers. One or more of the layers of the protective sleeve may be bonded together, or may not be bonded together. In embodiments, some, all or none of the layers of material of the protective sleeve may be bonded to another layer in the protective sleeve. In embodiments, some, all or none of the layers of material of the protective sleeve may be bonded to another layer in the protective sleeve. In embodiments, some, all or none of the layers of material of the protective sleeve may be joined together.

Various embodiments described below include a reflective layer such as a metallized Mylar® polyester film laminated to another material such as a Rip Stop Nylon to create a composite material. According to embodiments, the reflective layer may have a reflective surface (e.g. a surface which includes a thin metallic film which is deposited through metallization) and a non-reflective surface, or two reflective surfaces. In some embodiments where the reflective layer has one reflective surface, the composite may be manufactured such that the non-reflective surface is bound directly to the Rip Stop Nylon, such that the reflective surface remains exposed. In other embodiments where the reflective layer has one reflective surface, the composite may be manufactured such that that the reflective surface is bound directly to the Rip Stop Nylon such that the reflective surface is hidden. In embodiments where the reflective layer has two reflective surfaces, one reflective surface will be bound directly to the Rip Stop Nylon and hidden, and one will remain exposed. Thus, in embodiments of the protective sleeve which follow, a reflective surface may face outward (away from the electronic device), inward (toward the electronic device), or both inward and outward. The orientation of the reflective surfaces will depend on the particular application of the protective sleeve (e.g. whether it is intended to protect the device from heat, cold, or both). Further, the reflective surface(s) may be hidden (e.g. covered by another layer) or exposed. Not wishing to be bound by theory, it is the reflective surface(s) of the reflective layer which are believed to primarily trap/reflect infrared energy within or keep infrared energy out of the protective sleeve.

A two-layer embodiment of the invention provides an outer reflective layer and inner protective layer. The outer reflective layer may include Mylar® polyester film, such as a highly-reflective “continuous” metalized Mylar® polyester film, or aluminized polyester film laminated to a Rip Stop Nylon or similar material, and the emissivity of the outer layer may be in the range of about 0.05 to 0.40, such as less than 0.40, less than 0.30, less than 0.20, or less than 0.10. For example, the emissivity can be 0.1 to 0.2, or 0.02 to 0.35, or 0.01 to 0.25, or 0.04 to 0.15, and so on. Further, in embodiments, the outer metalized surface of the outer reflective layer has a reflectivity in the range of between 80% and 100%, with a preferred range between 90% and 100%. The inner protective layer may include a micro-fleece type material (lining) which is capable of protecting the touch screen on the device and preventing scratches.
